Abstract :
The fusion of rough set and fuzzy set has become one of the hot issues in the disposal of intelligence information in recent years. In this paper, fuzzy equivalence class on Δ-transitive compatible relation is introduced. A special Δ-transitivity, also referred to as Tm-fuzzy transitive compatible relation in information systems is created. On the basis, fuzzy rough set and its improvement are discussed respectively.
